IMPROVEMENT IN NAIL-DELIVERING MACHINES.

' Specification forming part of Letters Patent No. 145,755, datedDecember 23,1873; application led October 29, 1873. Y

To all whom it may concern:

Be it known that I, SrLAs S. PUTNAM, of Boston, in the county of Suffolkand State of Massachusetts, have invented an improved machine forreceiving, turning, and deliver-I ing forged or partially-madehorseshoe-nails to other machinery for afterward operating upon them, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings making part of thisspecification, in which- Figure l is a front elevation of my improvedmachine. Fig. 2 is a side elevation of the same. Fig. 3 is a verticalsection on the line x x of Fig. 2. Fig. et is a section on the line y yof Fig. l.

Forged or partially-made horseshoe-nails have been delivered tomachinery, for finishing or otherwise operating upon them, by acarrier-wheel which was provided with compartments to receive the nailsand jaws or nippers to hold them from dropping out during the revolutionof the wheel, the jaws being opened at the required times to release thenails and allow them to drop out.

This invention has for its object to provide a cheaper, more effective,and less complicated mechanism than that above described, and consistsin the combination of a carrier-wheel provided with one or more boxes orcompartments for receiving the nails, which are prevented from droppingout until they arrive in the proper position, with conductors and a ringor guard which surrounds the carrier-wheel, the latter being partiallyrotated alternately in opposite directions, or revolved intermittinglyin one direction, as preferred, while the rim or periphery of thecarrier-wheel intercepts the nail and retains it within the conductoruntil the box or compartment arrives beneath it.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the bed of the machine, from whichrise the supports a b of a circular frame or ring, B, at the back ofwhich are two cross-bars, c d, and at the point where these bars uniteis a long bearing, e, in which is supported a shaft, f, to one end ofwhich is secured a gear, C, and at the opposite end a carrierwheel, D,which is incloscd within the ring B, on the inside of which is a iiange,5, as seen in Fig. 4. Extending radially from the hub to the peripheryof the wheel D, and connecting them together, are two boxes orcompartments, g g, which are open at their outer ends, and are formed toreceive the nails as they drop point or head down singly from aconductor, E, at the top of the ring B, the nail in the conductorpassing through a notch or aperture, 6, in the ring, and resting on theperiphery of the wheel, asseen in Fig. 3, and it is thus retained withinthe conductor until one of the compartments g is brought under it, whenit drops therein and is carried round by the revolution of the weeeluntil it arrives in a position over a notch, 8, in the bottom of thering, and diametrically opposite to the notch 6, when it drops out ofthe compartment into a conductor, G, by which it is delivered to othermachinery for finishing or otherwise operating upon it; and it will beseen that the ring B serves as a guard to prevent the nail from droppingout as the carrierwheel is revolved, thus avoiding the necessity ofemploying jaws or nippers to hold the nail, as heretofore, and renderingthe machine less complicated and more certain in its action, and alsoreducing its cost. The half-revolution of the carrier-wheel serves toturn the nail so that it is dropped into the lower conductor Gr, withits head in a position exactly the reverse of that which it occupiedwhen in the upper conductor E. The carrienwheel is rotated half-wayround, first in one direction, and then in the other, so as to bring thecompartments g g alternately beneath the conductor E to receive a nail,by means of a toothed segment, t', at the end of a lever, H, whichengages with the gear C at the end of the shaft f, each compartmentbeing momentarily arrested previous to the direction of its' motionbeing reversed, on its arrival beneath the conductor E, or over theconductor Gr, which allows sufficient time for 'the nail to drop into orout of its compartment. The lever H is pivoted upon a stud projectingfrom the vertical bar c, and its lower arm is provided with a slot, 7c,in which ts a crank-pin, l, projecting from the face of a disk, I,secured to the inner end of a shaft, m, which has its bearing in astandard, K, and carries at its outer end a Wheel, L, by revolving whichthe lever H is vibrated to actuate the carrier-Wheel, as required.

'Instead of partially rotating the carrier- Wheel alternately inopposite directions, it may be revolved intermittingly in one directionby a ratchet-Wheel and .paWl, or other suitable device, and, instead ofemploying two boxes or compartments, g, as shown, one only, or a seriesof three or more, may be used, if preferred, in which latter case thecarrierwheel would be revolved intermittingly in one direction, theamount of each movement being made to correspond With the distancebetween the compartments.
